IMPROVEMENT IN DETACHING-HOQKS.

v'.ihe Schedule referred to in these Letters Patent and making part ofthe same.

To all whom. it may concern: v

.Beit known that we, JOSEPH Woon TUTTLE and JULIUs PETERSON, ofRochester, in the county Aof Monroe and State of New York, have jointlyinvented a certain new and useful Im'prowernent in Disengaging- Hooks,for `use on canal-boats, and other purposes, of which the following is aspecification, referring to the accompanying drawings.

' Nature of Invention.

Generai Description. In the drawings- Figure 1 is a side elevation, andFigure 2, a plan.

A is the shank of the hook, having pivoted at one4 end the clevis B, andat the other the hook-armi C.

Between these is also pivoted the swinging catch D, which is preferablyin the form oi'a link, and turns up over the end of the hook-'arm tohold itin place, as clearlyshown.` Instead of this form itmay be made ofany that will produce the same result.

The hook-arm bends forward in such a manner as to overlie the shank, andthe connection of the swingvingcatch with it is such that it may bedrawn off to disengage the hookarm.

At the rear end of the device a socket, a, is formed, of suitable 4sizeand' shav e to receive a loose ring, G.

Thus arranged, the draft-rope H may be attached either to the ring G, asin tig. 1, or to the clevis B, as in fig. 2, the drawings showing thepositions reversed for different uses.

In those different uses the cord I, which attaches to the pawl tooperate it, also passes in different drec tions, as shown.

In Iig. l1 the hook is shown as adjusted in the position for a personstanding at a distance, in thestern wwwof the boat, to disengage thehook. This would be convenient for the steersman.

In fig; 2 it is 'shown as adjusted in the position for the driver to,disengage the swinging catch, he stand- "ing on the bank of the canal,and a distance forward of the boat.

The essential novelty in this case is the adaptation of the portablehook, as above described, whereby it is applicable to'nse vineitherdi'ection. On canals, especially, it is of very great advantage, as thepower to 'dsengage may be transferred at pleasure from the ste'ersrnan'to the driver, which is frequently desirable inpassing other boats orgoing upon an unobstructed way. To do this it is only necessary tochange ends of the hook.

By its portability and capability of attachment at' either end it alsois adapted to many other uses, and may be interposed at anyy position ina continuous chain, an effect which we believe is new. We can also useit as a coupling to uncouplc at will on' any chain or cord subject tostrain.

We are aware that in other devices n. swinging catch has before beenused to disconnect a part serving as an attachment to a cord or chain.

'We are also aware that a hook-arm for releasing a cord or chain hasbefore been used. Such broadly we do not claim; but

What we claim as our invention is The shank constructed as herein shownand described,

lprovided with a hinged arm, O, swinging catch D, and olevis -B, allcombined and arranged as herein shown and described.

In witness whereof we have hereunto signed our names in the. presence oftwosubscribingwitnesses.
